Abstract

본 발명 표시 장치는 대향면들에 안내층(7)이 적용된 진극층(4,5)들을 구비하면서 대향되게 위치된 2개의 플레이트(1,2)들로 이루어진 기판들과, 플레이트들의 선단부들 사이에 구비된 밀봉재료(3) 및, 플레이트들과 밀봉재료 사이의 공간에 채워진 액정 재료(6)로 구성된 표시 셀을 포함한다. 본 발명 표시 장치에서는, 액정 재료가 소망하는 패턴에 따라 폴리머 네트워크로 국부적으로 형성되고, 이에 따라 단일 전극들과 전도트랙들이 서로 교차하는 위치들에서 화상 형성이 요구되지 않는다. 현 액정 재료의 전환 역치를 국부적으로 증가시킬 수 있기 때문에 충분한 자유도를 갖고서 원하는 화소들의 패턴을 설계할 수 있다.
